Lucas Alderson,
On a scale of 1-10 with 1 being the easiest, they are a 1 if that. They are one of the easiest things to keep. If they are happy, they will even reproduce for you.
Welcome to the board, we hope you enjoy your time here. What kind of lighting do you have. If you are running regular flourescent lights, keep them between the middle and top of the tank.
Best of luck.
